VR Tracker is an Open Source 3D position tracking system for Virtual Reality. This device aims at improving VR experiences by allowing the user to move around in a large environnement. It uses at least 2 infrared tracking cameras (PixyCam), which are sending 2D positions of an infrared dot via Wifi thanks to an ESP8266 chip. Those datas can be processed in a phone or PC using Unity and the OpenCV library to triangulates the position and get a 3D position from two 2D positions.

Old Remote is a side project of mine. It is a small box placed next to your TV which connects automatically to your smartphone via Bluetooth 4.0. You can record all your remotes into your smartphone and use it instead of your remotes. When in range, notifications for available remotes pop up in your phone. You can also use it to control your DSLR camera for example, set up macros to take a picture every minute or start all your home cinema in one single touch ! With Old Remote, you won’t have to look for your remotes, or new batteries anymore ! If you want to be part of the project, Android and iOS developers would be very useful. This is a full open source project and files we be available soon, you might want to check the latest posts here : Old Remote Blog

The Low Cost ECG is, as its name says, a 10$ ECG with a screen to give the heartbeat and a jack connector to plug it in a PC and be able to get the curves ! E.C.G Low Cost is an initiative started by the humanitarian association Projet PC2. I am Vice President of what we would call “computer science missions”, and the E.C.G Low Cost is one of the project I am working on. Each summer we travel to a village in a third world country to give computer science training in schools, but also training in hospital concerning medical equipment and prevention mainly. This is why we started building our own ECG. The project is currently under development, and should be operational by summer 2015. We are using an Arduino for the signal treatment, a small LCD screen and some amplifiers, and that’s it ! It is running on two 9 volts batteries. I would like to give all credit to “birdyberth” and its Instructables, which our circuit is mainly based on.
